1. 2/5 + -3/5=
2. M - 7/18 = -5/18 (must reduce)
3. R + 7/12 = -5/12
What answers did you get? We'll be glad to check them for you.
I will do one.
2) M-7/18=-5/18 add seven eights to each side.
M=(7-5)/18= 2/18= 1/9
I will be happy to check your work on the others.
Okay. For number 1. I got -1/5
Number 2. i got 1/9
number 3 i got -1
Great! You're right! :-)
Really thanks alot!!!
To solve these equations involving fractions, you'll need to perform basic operations like addition, subtraction, and multiplication. You may also need to take into consideration reducing or simplifying the fractions if the problem requests it. Let's solve each of these equations step by step:
1. To add fractions, you need to find a common denominator. In this case, the common denominator is 5 since both fractions have 5 as their denominator. So, the equation becomes:
2/5 + (-3/5) = (2 + -3)/5 = -1/5
2. Let's solve for M in the equation M - 7/18 = -5/18. Here, we need to isolate the variable M. To do this, we can add 7/18 to both sides of the equation to cancel out the -7/18 on the left side:
M - 7/18 + 7/18 = -5/18 + 7/18
M = 2/18
Now, let's reduce this fraction. Both the numerator and denominator are divisible by 2. Dividing both by 2, we get:
M = 1/9
3. Following a similar approach, let's solve for R in the equation R + 7/12 = -5/12. To isolate R, we can subtract 7/12 from both sides:
R + 7/12 - 7/12 = -5/12 - 7/12
R = -12/12
Simplifying, we see that -12/12 is equal to -1. Therefore:
R = -1
Note: When reducing fractions, you divide both the numerator and denominator by their greatest common factor (if any) to simplify the fraction.
