Given, 1 10 by 2 To divide the first fraction by the second fraction, multiply the first fraction by the reciprocal of the second fraction. Thus, 1 10 ÷ 2 = 1 10 × 1 2 = 1 20 Hence, the required answer is 1 20 .

Aachal Verma bought 3 7 kg pea and 4 9 kg wheat. How much total cereals did she buy ?

Given, The kilograms of pea Aachal bought = 3 7 k g The kilograms of wheat Aachal bought = 4 9 k g Let the total cerals she bought be x k g To find the total cereals bought, add 3 7 and 4 9 . ⇒ 3 7 + 4 9 = x ⇒ 27 + 28 63 = x ⇒ 55 63 = x Therefore, the total cereals Aachal bought 55 63 kg .

An electricity pole is 11 2 3 m long. If a length of 2 1 3 m is under the ground, how much part of the pole is above the ground?

Given, Length of electricity pole is 11 2 3 = 35 3 m Length of electricity pole under the ground is 2 1 3 = 7 3 m Let the length of the pole above the ground is x m So, ⇒ 7 3 + x = 35 3 ⇒ x = 35 3 - 7 3 ⇒ x = 35 - 7 3 ⇒ x = 28 3 = 9 1 3 Thus, the length of the electricity pole above the ground is 9 1 3 m .

A board of 3 7 16 cm thick is glued to a board of 4 3 8 cm thick. What is the combined thickness of the boards?

Given, A board of 3 7 16 cm thick is glued to a board of 4 3 8 cm thick. Let the combined thickness of the boards is x c m . So, ⇒ 3 7 16 + 4 3 8 = x ⇒ 55 16 + 35 8 = x ⇒ 55 + 70 16 = x ⇒ 125 16 = 7 13 16 = x Thus, the length of the board is 7 13 16 c m

A vessel had 4 1 4 litres of milk. Out of it, a cat drank 3 8 litres. How much milk was left in the vessel?

Given, Milk in a vessel is 4 1 4 litres Cat drank milk 3 8 litres Let the milk left in the vessel is x litres. So, ⇒ x + 3 8 = 4 1 4 ⇒ x + 3 8 = 17 4 ⇒ x = 17 4 - 3 8 ⇒ x = 34 - 3 8 ⇒ x = 31 8 = 3 7 8 Thus, milk left in the vessel is 3 7 8 litres.

Rahul can walk 5 2 5 km in an hour. How much distance will he cover in 3 1 3 hours ?

Given, Rahul cover distance in one hour 5 2 5 k m Now, Total distance cover in 3 1 3 hours is 5 2 5 × 3 1 3 = 27 5 × 10 3 = 18 Therefore, total distance cover by Rahul in 3 1 3 hours is 18 k m .
