Plz help
Sure, I can help you with that. Here are the step-by-step solutions to each of the equations:
1. n × 4/5 = 3/4
To solve for n, we need to isolate it on one side of the equation. We can do this by multiplying both sides of the equation by the reciprocal of 4/5, which is 5/4:
n × (4/5) × (5/4) = (3/4) × (5/4)
Simplifying the equation, we get:
n = 3/4 × 5/4
n = 15/16
So, the solution is n = 15/16.
2. d/5 = 4
To solve for d, we need to isolate it on one side of the equation. We can do this by multiplying both sides of the equation by 5:
(d/5) × 5 = 4 × 5
Simplifying the equation, we get:
d = 4 × 5
d = 20
So, the solution is d = 20.
3. 2 1/4r = 10
To solve for r, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 2 1/4. We can convert 2 1/4 to an improper fraction first:
2 1/4 = (8/4) + (1/4) = 9/4
Dividing both sides of the equation by 9/4, we get:
(2 1/4r)/(9/4) = 10/(9/4)
Simplifying the equation, we get:
r = (10/(9/4)) × (4/9)
r = 40/36
r = 10/9
So, the solution is r = 10/9.
4. h/26 = 5
To solve for h, we need to isolate it on one side of the equation. We can do this by multiplying both sides of the equation by 26:
(h/26) × 26 = 5 × 26
Simplifying the equation, we get:
h = 5 × 26
h = 130
So, the solution is h = 130.
5. 6/7k = 6
To solve for k, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 6/7:
(6/7k)/(6/7) = 6/(6/7)
Simplifying the equation, we get:
k = 6/(6/7)
k = 6 × (7/6)
k = 7
So, the solution is k = 7.
6. 4/5x for x = 5/8
To evaluate the expression 4/5x when x = 5/8, we substitute x with 5/8:
4/5(5/8) = 4/5 × 5/8
Multiplying the fractions, we get:
(4/5) × (5/8) = 20/40 = 1/2
So, the solution is 1/2.
7. he4/9 for h = 5 1/3
To evaluate the expression he4/9 when h = 5 1/3, we substitute h with 5 1/3:
(5 1/3)e(4/9) = (16/3)e(4/9)
We cannot simplify this expression further without knowing the value of e.
8. J ÷ 3 1/2 for j = 9/10
To evaluate the expression J ÷ 3 1/2 when j = 9/10, we substitute j with 9/10:
(9/10) ÷ (3 1/2) = (9/10) ÷ (7/2)
Dividing fractions, we invert the second fraction and multiply:
(9/10) × (2/7) = 18/70 = 9/35
So, the solution is 9/35.
9. w ÷ 7 1/2 for w = 5 5/6
To evaluate the expression w ÷ 7 1/2 when w = 5 5/6, we substitute w with 5 5/6:
(5 5/6) ÷ (7 1/2) = (35/6) ÷ (15/2)
Dividing fractions, we invert the second fraction and multiply:
(35/6) × (2/15) = 70/90 = 7/9
So, the solution is 7/9.
10. 8 1/3s for s = 4 1/2
To evaluate the expression 8 1/3s when s = 4 1/2, we substitute s with 4 1/2:
(8 1/3)(4 1/2) = (25/3)(9/2)
Multiplying fractions, we get:
(25/3) × (9/2) = 225/6 = 37 1/2
So, the solution is 37 1/2.
I hope this helps! If you have any more questions, feel free to ask.
Certainly! I can help you solve these equations step by step. Let's go through each one:
1. To solve the equation: n×4/5=3/4
- Multiply both sides of the equation by 5/4 to eliminate the fraction (5/4 is the reciprocal of 4/5):
(n × 4/5) × (5/4) = (3/4) × (5/4)
- Simplify:
n = 15/16
2. To solve the equation: d/5 = 4
- Multiply both sides of the equation by 5 to isolate the variable d:
(d/5) × 5 = 4 × 5
- Simplify:
d = 20
3. To solve the equation: 2 1/4r = 10
- We need to convert the mixed number to an improper fraction first:
2 1/4 = (2 × 4 + 1) / 4 = 9/4
- Divide both sides of the equation by 9/4 to isolate the variable r:
(2 1/4r) ÷ (9/4) = 10 ÷ (9/4)
- Simplify:
r = (10 × 4) / 9 = 40/9
4. To solve the equation: h/26 = 5

(h/26) × 26 = 5 × 26
- Simplify:
h = 130
5. To solve the equation: 6/7k = 6

- Substitute x = 5/8 into the equation and simplify:
(4/5) × (5/8) = 1/2
7. To solve the equation: he4/9 for h = 5 1/3
- Convert the mixed number to an improper fraction:
5 1/3 = (5 × 3 + 1) / 3 = 16/3
- Substitute h = 16/3 into the equation:
(16/3)e4/9 = (16 × 4) / (3 × 9) = 64/27
8. To solve the equation: J÷ 3 1/2 for j = 9/10
- Convert the mixed number to an improper fraction:
3 1/2 = (3 × 2 + 1) / 2 = 7/2
- Substitute j = 9/10 into the equation:
(9/10) ÷ (7/2) = (9/10) × (2/7) = 18/70 = 9/35
9. To solve the equation: w÷7 1/2 for w = 5 5/6
- Convert the mixed number to an improper fraction:
5 5/6 = (5 × 6 + 5) / 6 = 35/6
- Substitute w = 35/6 into the equation:
(35/6) ÷ (7/2) = (35/6) × (2/7) = 5/6
10. To solve the equation: 8 1/3s for s = 4 1/2
- Convert the mixed number to an improper fraction:
4 1/2 = (4 × 2 + 1) / 2 = 9/2
- Substitute s = 9/2 into the equation and simplify:
