Answer 1

Answer:

First we will make the denominator same by finding LCM

LCM of 8and 5 is 40.

therefore the question becomes

25/40 + ( -24/40)

= 25 - 24/40

= 1/40

Answer 2

Answer:

Multiply the numerators of the fractions (the top numbers).

2. Multiply the denominators of the fractions (the bottom numbers).

3. Simplify the fraction if needed to the lowest terms.

For example:

(i) 3/7 × 4/5

= (3 × 4)/(7 × 5)

= 12/35

(ii) 7/3 × 5/2

= (7 × 5)/(3 × 2)

= 35/6

(iii) 5 × 3/7

= 5/1 × 3/7

= (5 × 3)/(1 × 7)

= 15/7

(iv) 5/12 × 9

= 5/12 × 9/1

= (5 × 9)/(12 × 1)

= (5 × 3)/(4 × 1)

= 15/4
