Simplify:
(i) 1 / 4 of 227 ÷ 3 / 5
(ii) 114 × 1 / 2 ÷ 113
(iii) 617× 0 × 538
(iv) 3 / 4 × 113 ÷ 3 / 7 of 258
(v) 214 ÷ 2 / 7 of 113 × 2 / 3
(i) 1 / 4 of
227 ÷ 3 / 5
The given expression can be simplified as follows:
1 / 4 × 16 / 7 ÷ 3 / 5 = 4 / 7 ÷ 3 / 5
= (4 × 5) / (7 × 3)
= 20 / 21
Hence, 20 / 21 is the simplified form of the given expression
(ii) 114 × 1 / 2 ÷ 113
The given expression can be simplified as follows
114 × 1 / 2 ÷ 113
= 5 / 4 × 1 / 2 × 3 / 4
= 5 / 8 × 3 / 4
= 15 / 32
Hence, 15 / 32 is the simplified form of the given expression
(iii)
617 × 0 × 538
The given expression can be simplified as follows
617 × 0 × 538 = (43 × 0 × 43) / (7 × 0 × 8)
= 0
Hence, 0 is the simplified form of the given expression
(iv) 3 / 4 ×
113 ÷ 3 / 7 of 258
The given expression can be simplified as follows
3 / 4 ×
113 ÷ 3 / 7 of
258 = 3 / 4 × 4 / 3 ÷ 9 / 8
∵ 3 / 7 of
258 = 3 / 7 × 21 / 8 = 9 / 8
= 3 / 4 × 4 / 3 × 8 / 9
= 8 / 9
Hence, 8 / 9 is the simplified form of the given expression
(v)
214 ÷ 2 / 7 of
113 × 2 / 3
The given expression can be simplified as follows
[2 / 7 ofWe get
= 9 / 4 ÷ 8 / 21 × 2 / 3
= 9 / 4 × 21 / 8 × 2 / 3
= 63 / 16
= 31516
Hence, 31516 is the simplified form of the given expression
