Question

Help me I am suffering from math T-T

Answer 1

7/10

Explanation:

3 1/5= 16/5

2 1/2= 5/2

16/5=32/10

5/2=25/10

32/10 - 25/10 = 7/10

Answer 2

7/10

Explanation:

Step 1 : convert mixed fraction to improper fractions.

Step 2: Find Least common denominators.

Step 3 : Find equivalent fractions and subtract.

`3(1)/(5)-2(1)/(2)= ((3*5)+1)/(5)-((2*2)+1)/(2)\\`

`= (16)/(5)-(5)/(2)\\\\=(16*2)/(5*2)-(5*5)/(2*5)\\\\=(32)/(10)-(25)/(10)\\\\= (32-25)/(10)\\\\= (7)/(10)`
