1.Subtract and Simplify
2/3 - 1/5 = 1/2
2.Multiplu
4/5 * 6/7 = 24/35
3.subtract write an mixed numeral for the answear
20, 1/9
14, 7/15
Please see the last answer for the correction for 1.
2. is correct.
3. 20 1/9 - 14 7/15 =
You need to find a common denominator. 45 is divisible by 9 and 15
20 1/9 - 14 7/15 = 20 5/45 - 14 21/45
Now we need to change the first number to get a fraction larger than 21/45
20 5/45 = 19 50/45
19 50/45 - 14 21/45 = 5 29/45
Is this correct?
1. 1/3 > 7/10
2. prime factors of 441 are 1,3,9,7,49,441
3. prime factors of 27 are 1,3,6,9,27
1. 1/3 > 7/10
This is not correct. 1/3 is not greater than 7/10.
30 is the common denominator -- so 10/30 is less than 21/30.
2. Right!
3. Right!
1/3 = 10/
(4.9*10^-6)*(2*10^-4)
To subtract mixed numerals, you need to first convert them to improper fractions and then subtract them. Here's how to do it for the given question:
3. Subtract and write a mixed numeral for the answer:
To subtract mixed numerals 20 1/9 and 14 7/15, follow these steps:
Step 1: Convert both mixed numerals to improper fractions.
20 1/9 is equivalent to (20 * 9 + 1)/9 = 181/9.
14 7/15 is equivalent to (14 * 15 + 7)/15 = 217/15.
Step 2: Subtract the two improper fractions.
181/9 - 217/15 = (181 * 15 - 217 * 9)/(9 * 15) = (2715 - 1953)/135 = 762/135.
Step 3: Simplify the fraction if possible.
The greatest common divisor between 762 and 135 is 9, so divide both numerator and denominator by 9.
762/135 = (762/9)/(135/9) = 84/15.
Step 4: Write the answer in mixed numeral form.
To convert the improper fraction 84/15 to a mixed numeral, divide the numerator (84) by the denominator (15): 84 ÷ 15 = 5 with a remainder of 9.
Therefore, the answer is 5 9/15.
However, we can simplify this mixed numeral further.
The greatest common divisor between 9 and 15 is 3, so divide both numerator and denominator by 3.
5 9/15 = 5 (9/3)/(15/3) = 5 3/5.
So, the final answer is 5 3/5.
