.05 x 5 - .005 x 5 =?

Correct Answer: .00375

Explanation:

Given expression = .01 x .3 ÷ .4 x .5
= .0015 ÷ .4
= .00375

Correct Answer: 7 / 3

Explanation:

Given expression = (48 - 12 x 3 + 9) / (12 - 9 ÷ 3)
= (48 - 36 + 9) / (12 - 3)
= 21 / 9
= 7 / 3

Correct Answer: 1.45

Explanation:

Given expression = (69 - 14 x 3 + 2) / [ 9 x 5 - (5)²]
= (69 - 42 + 2) / (45 - 25)
= 29 / 20
= 1.45

Correct Answer: 300

Explanation:

Given expression = [(272 - 32) (124 + 176)] / (17 x 15 - 15)
= (240 x 300 ) / 240
= 300

Correct Answer: 15 / 11

Explanation:

Given expression = (7 + 7 + 7 ÷ 7) / (5 + 5 + 5 ÷ 5)
= (14 + 1) / (10 + 1)
=15 / 11

Correct Answer: 3.2

Explanation:

Given expression = 4 - 3.6 ÷ 4 + 0.2 x 0.5
= 4 - 0.9 + 0.1
= 3.2

Correct Answer: 0.35

Explanation:

Given Exp. = 0.5 x 0.5 + 0.5 ÷ 5
= 0.25 + 0.1
= 0.35

Correct Answer: 4

Explanation:

Given expression = 8 ÷ 4 (3 - 2) x 4 + 3 - 7
= 8 x (1/4) x 1 x 4 + 3 - 7
= 8 + 3 - 7
= 4

Correct Answer: 9

Explanation:

Given expression = (20 ÷ 5) ÷ 2 + (16 ÷ 8) x 2 + (10 ÷ 5) x (3 ÷ 2)
= (4 / 2) + (2 x 2) + 2 x (3 / 2)
= 2 + 4 + 3
= 9

Correct Answer: None of these

Explanation:

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