(1 ³/ ₅ - 2/3 ÷ 12/13 + 7/5 x 1/3) is equal to?

Correct Answer: 101/2

Explanation:

Given expression = 108 ÷ 36 of 1/3 + 2/5 + 3³/₄
= 108 / 12 + 2 / 5 x 15 / 4
= 9 + 3 / 2
= 21 / 2
= 10¹/₂

Correct Answer: 81

Explanation:

Given expression = 171 ÷ 19 x 9
= 171 / 19 x 9
= 9 x 9
= 81

Correct Answer: 4505

Explanation:

Given expression = 5005 - 5000 ÷ 10.00
= 5005 - 500
= 4505

Correct Answer: 14

Explanation:

Given Expression = 7 + 7 ÷ 7 x 7
= 7 + 7 x (1/7) x 7
= 7 + 7
= 14

Correct Answer: None of these

Explanation:

Given Expression = 3120 ÷ 26 + 13 x 30
= 120 + 13 x 30
= 120 + 390
= 510

Correct Answer: 21/3

Explanation:

Let 13/4 + 25/6 + N + 1/4 = 10, then
N = 10 - (13/4 + 25/6 + 1/4)
= 10 - (39 + 50 + 3)/12
= 10 - 92/12
= 7/3
= 2¹/₃

Correct Answer: 12

Explanation:

Given expression = 48/12 x (3/2 ÷ 1/2)
= 4 x (3/2) x 2
= 12

Correct Answer: 3

Explanation:

Given expression = 10 - [ 9 - {8 - 1}] - 5
= 10 - [9 - 7] - 5
= 10 - 2 - 5
= 3

Correct Answer: 14/7

Explanation:

Given expression = 1 + 1 ÷ {1 + 1 ÷ (1 + 1/3)}
= 1 + 1 ÷ { 1 + 1 ÷ 4/3}
= 1 + 1 ÷ { 1 + 3/4}
= 1 + 1 ÷ 7/4
= 1 + 1 x 4/7
= 1 + 4/7
= 1⁴/₇

Correct Answer: 9/4

Explanation:

Given expression = 3/2 x 4/3 + 1/4
= 2 + 1/4
= 9/4
