Answer:

ANSWER: 1

21/5+23/10

L . C. M . is 10

so,(41+23)/10

= 64/10

ANSWER: 2

40×10/23

=400/23

=17whole 9/23

Answer 2

a)

First change the mixed fractions into normal fractions. Then do lcm of the denominators and next add them with proper process.

∴ 4 1/5 + 2 3/10

= 21/5 + 23/10

= (21 × 2 + 23 × 1)/10 [ lcm of 5, 10 is 10 ]

= (42 + 23)/10

= 65/10

= 6 5/10

b)

First change the mixed fraction into normal fraction. Use the law: a ÷ b/c = a × c/b.

∴ 40 ÷ 2 3/10

= 40 ÷ 23/10

= 40 × 10/23

= 400/23

= 17 9/23
