Now,
= 21 3/5 – 15 1/10
= 108/5 – 151/10
= 216 – 151/10
= 65/10
So, the remaining length now is 65/10 m
(d) Given i the question,
7 1/4 – 3 4/5 and 17 1/2 – 9 1/3
Now,
= 7 1/4 – 4/5
= 29/9 – 19/5
= 145 – 76/20
= 69/20
= 69/20 × 3 = 207
= 49/6 × 60 = 980
∴ 17 1/2 – 9 1/3
= 35/2 – 28/3
= 105 – 56/6
= 49/6
So, the last one is greater.
(e) Marbles black and article
= 1/3 + 1/2
= 2 + 3/6
= 5/6
∴ Remaining,
= 1 – 5/6
= 6 – 5/6
= 1/6
Fraction of green marbles is 1/6

= Rs. 50000
(e) According to the question,
Park has perimeter of = 2 1/3 kilometres.
If a boy takes = three rounds of it
Now, Perimeter
= 2 1/3 km
= 7/3 km
∴ Boy run
= 3 × 7/3
= 7 km
So, the boy will run 7 kilometre.
(f) In the given question,
A grocery store received 112 bags on a day.
Bags contains vegetables = 1/2
potatoes is = 1/7
Now,
Bags contains vegetable
= 1/2 × 112
= 56 kg
∴ He received potato
= 1/7 × 8/56
= 8 bags
So, the store receive 8 bags potato.

Question no – (2)
Solution :
(a) In the given question,
There is 15 kg of sugar
sugar into one packet = 1/7
Packets can be made = ?
Now, Each packet contains,
= 15 × 1/7
= 15/7 kg
∴ Packet can be made from 15 kg
= 15 ÷ 15/7
= 15 × 7/15 (Change ÷ into × and invert 15/7)
= 7 packet
So, 7 packets can be made.
(b) 4/9 of the distance cover is,
= 8 minute …(according to the question)
∴ 1 of the distance cover is,
= 8 × 9/4
= 18 minute
So, time take to reach grandma’s house is 18 minute.
(c) Given in the question,
A mother distributes sweets = 1/4 kg
Total children = 5
Now,
= 1/4 kg
= 1000/4
= 250 g
∴ Each child get
= 250/5
= 50 g
Thus, each child will get 50 g of sweets.
(d) = 3/12 ÷ 9/84 …(According to the question)
= 3/12 × 84/9 ….(Change ÷ into × and invert 9/84)
= 7/3
Now, = 7/3 × 9/14
= 3/2
(e) = 3.50 = 350 paisa (∵ we know, 1 rupee = 100 paisa)
= 10 × 35
= 10 × 70/2
= 700/2
So, 3.50 as a fraction of ten rupees is 700/2
(f) In the question,
Cost of 6 2/3 kg of rice is = ₹24 2/3.
Cost of 1 kg of rice = ?
Now,
= 6 2/3
= 20/3 ….(change mixed numbers into improper fractions)
∴ 20/3 kg cost 75/3
∴ 1 kg cost 75/3 ÷ 20/3
= 75/3 × 3/20 …(Change ÷ into × and invert 20/3)
= 15/4
So, the cost of 1 kg of rice will be Rs. 15/4
