Answer 1

Question 11

Converting mixed fractions to improper fractions.

2 ½ = (2x2)+1 = 5/2 and ₹58¾ = (58 x 4)+3 = 235/4

Applying the unitary method:

5/2 kg→ ₹235/4
1 kg → x

x = (235/4) / (5/2)
x = (235/4) x (2/5)
x = (47/2)

1 kg of sugar = ₹23 ½ or ₹47/2 or ₹23.5

Question 12

Converting mixed fractions to improper fractions.

94 ½ m = 189/2 m and 2 ¼ m = 9/4 m

(189/2) / (9/4) = 42

Total 42 uniforms can be made.

Question 13

Converting mixed fractions to improper fractions.

137 ½ kg = 275/2 kg

(275/2) / 50 = 11/4 kg

Each farmer receives 11/4 kg or 2.75 kg of seeds.

Question 14

Converting mixed fractions to improper fractions.

385 ⅘ km = (1929/5) km
4 ¾ h = (19/4) h

Average speed = Total distance / Total time
= (1925/5) / (19/4)
= 1540/19 km/h
≈ 81 km/h

Question 15

Converting mixed fractions to improper fractions.

3 ⅖ = (17/5) and 120 7/10= (1207)/10

Applying the unitary method:

(17/5)m = ₹(1207/10)
1 m = x

x = (1207/10) x 1 / (17/5)
x = 71/2 or x = 35.5

Cost of 1m of cloth = ₹71/2 or ₹35.5
