=  13 4 ÷ 5 4 - 1 2 30 - 1 12 =  13 4 ÷ 5 4 - 29 24

 

 =  13 4 ÷ 30 - 29 24=78

Correct Answer: 95°F

Explanation:

Let F and C denotes the temparature in Fahrenheit anid Celcsius respectively.

Then, (F - 32) /(212 - 32) = (C - 0)/(100 - 0),  if c = 35, then F = 95.

Correct Answer: 0

Correct Answer: 100

Correct Answer: 20

Explanation:

We know that 

$$\begin{gathered} 40 % = 40 100 = 2 5 \\ ? 2 5 x 24 4 x ? = 48 \\ ? = 48 x 5 x 4 2 x 24 = 20 \end{gathered}$$

Correct Answer: -4 (1/17)

Explanation:

Given fraction is 5 (2/7) - 3 (1/14) - 2 (1/14) - 1 (1/7) = ? + 3 (1/17) 

It can be written as 

(5 - 3 - 2 - 1) + (2/7 - 1/14 - 1/14 - 1/7) = ? +  3 (1/17) 

-1 + 0 - 3 (1/17) = ?

=> ? = -4 (1/17)
