No. 1 is actually correct. Nice work!

In No. 2, it's much easier to tackle the problem sentence by sentence. In the first sentence, we are given that Val has 6 yards of fabric. In the next sentence, we are given that she uses 1/3 of that piece of fabric to make a shirt. Let's calculate how much she has left now.

6 x (1/3) = 2
Val used up 2 yards, meaning she has 4 yards left.

The next sentence indicates that she uses 3/8 of what she has left, which is 4 yards of fabric. We can apply the same method as the first step.

3/8 x 4 = 3/2

She used up 1.5 yards to make a shirt for her sister, meaning she has 2.5 yards left.

Final Answer: 2.5 yards of fabric

How do I solve -2m=16m-9

Brums [2.3K]

-2m = 16m - 9

First, take '16m' from both sides.
$-2m - 16m = -9$
Second, add '-2m - 16m' to get '-18m'.
$-18m = -9$
Third, divide both sides by '-18'.
$m = \frac{-9}{-18}$
Fourth, change the fraction into a negative.
$m = \frac{9}{18}$
Fifth, find the GCF of 9 and 18.
The GCF is 9.
Sixth, divide the numerator by the GCF.
$9$ ÷ $9 = 1$
Seventh, divide the denominator by the GCF.
$18$ ÷ $9 = 2$
Eighth, rewrite the fraction in simplest form.
$m = \frac{1}{2}$

Answer as fraction: $m = \frac{1}{2}$
Answer as decimal: $m = 0.5$
