Question

-3 2/5 + b= 8 1/5 @iGreen

Answer 1

We gotta add \(3 \dfrac{2}{5}\) to both sides.

\(8 \dfrac{1}{5} + 3 \dfrac{2}{5}\)

These have the same denominator..so we just have to switch then both into improper fractions.

Answer 2

Can you switch them both into improper fractions?

Answer 3

41/5 + 17/5

Answer 4

Yep, you got it!

Now add them.

Answer 5

41 + 17 = ?

Answer 6

58/5

Answer 7

Yep, you got it..now convert back to mixed number.

Answer 8

11 3/5

Answer 9

Yep! :D

Outstanding work.

Answer 10

2 more?

Answer 11

Yep, I think I can do that..

Answer 12

-7/3n=-42

Answer 13

You have to divide -7/3 to both sides, or multiply by its reciprocal..

\(-7/3n = -42\)

\(n = -42 \times -3/7\)

Answer 14

Multiply that, what do you get?

Answer 15

donno

Answer 16

notsure

Answer 17

\(-\dfrac{42}{1} \times -\dfrac{3}{7} \rightarrow \dfrac{-42 \times -3}{-1 \times -7}\)

Can you simplify that?

Answer 18

-126/7

Answer 19

Yep, now divide that.

Answer 20

Actually it would be 126/7

Answer 21
