Answer 1

Answer:

(i) 5/11 of 4/5 of 22kg

= 5/11 × 4/5 (of means ×)

= 4/11

= 4/11 of 22kg

= 36.36% (we will estimate it to 36%)

= 36% of 22kg

= 7.92 kilograms

(ii) 2 5/9 - 2 1/6 + 4 3/4

⇒ 2 5/9 = 9 × 2 + 5 = 18+5 = 22/9

⇒ 2 1/6 = 6 × 2 + 1 = 12 + 1 = 13/6

⇒ 4 3/4 = 4 × 4 + 3 = 16+3 = 19/4

⇒ 22/9 - 13/6 + 19/4

We have to make the denominators equal

LCM of 9, 6 & 4 = 36

⇒ 22/9 = 22 ×4/ 9 × 4 =

⇒ 13/6 = 13 × 6 / 6 × 6 =

⇒ 19/4 = 19 × 9/ 4 × 9 =

As per the BODMAS rule = 78/36 + 171/36 -88/36

= 78 + 171 - 88 /36

⇒ 88/36 = 22/9

(iii) 1,100.997

(iv) 0.77
