Question

simplify 9 1/2 +3 2/5 +5 2/3​

Answer 1

Answer:

1. 3 1/3 ÷ 5/3 - 1/10 of 2 ½ + 7/4

Solution:

3 1/3 ÷ 5/3 - 1/10 of 2 ½ + 7/4

= (3 × 3 + 1)/3 ÷ 5/3 – 1/10 of (2 × 2 + 1)/2 + 7/4

= 10/3 ÷ 5/3 - 1/10 of 5/2 + 7/4

[‘of’ simplified]

= 10/3 × 3/5 – ½ × ½ + 7/4 [‘÷’ simplified]

= 2/1 - ¼ + 7/4 [‘×’ simplified]

= (2 × 4)/1 × 4) - (1 × 1)/4 × 1) + (7 × 1)/4 × 1)

= 8/4 - ¼ + 7/4

[Now the denominators are same of all the fractions]

= (8 – 1 + 7)/4 [‘+’ and ‘-‘ simplified]

= 14/4

= 7/2

Answer 2

Step-by-step explanation:

(9 1/2) + (3 2/5) + (5 2/3)

19/2+17/5+17/3

By finding their common factor we get 30.

(19×15/2×15) + (17×6/5×6) + (17×10/3×10)

285/30 + 102/30 + 170/30

285+102+170/30

557/30 = 18 17/30
