Question

1.(2/13) /(1/7)
2.(3/4+2/5)/(3/4-2/5)

Answer 1

1) 1.07
2) 3.28this will be the answer ti this

Answer 2

Here are your answers:

1. 2/13 ÷ 1/7

2/13 × 7/1 <--- Make sure to use KCF: (Keep Change Flip)

2 × 7 = 14

13 × 1 = 13

= 14/13

Divide to equal $1\frac{1}{13}$

2. 3/4 + 2/5 ÷ 3/4 - 2/5

According to PEMDAS you have to add 3/4 and 2/5 first:

3 × 5 = 15

4 × 5 = 20

+

2 × 4 = 8

5 × 4 = 20

15 + 8 =23

= 23/20

Divide to equal $1\frac{3}{20}$

Next part:

3 × 5 = 15

4 × 5 = 20

-

2 × 4 = 8

5 × 4 = 20

15 - 8 =7

=7/20

Now last part:

1 3/20=23/20

23/20 ÷ 7/20 = <--- Make sure to use KCF: (Keep Change Flip)

23/20 × 20/7

23 × 20 = 460

20 × 7 = 140

140 ÷ 460 =

Divided to equal $3\frac{2}{7}$

Hope this helps!
