Answer:
Simplification of Fractions
In simplification of fractions parenthesis can also be used. The three parenthesis (1st), {2nd}, [3rd] are used commonly.
Examples on simplification of fractions:
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
