Question

3/5 = 24/40 =?/60. what comes at the question mark?​

Answer 1

Step-by-step Solution:

Let the "?" be known as "x".

Given equation:

3/5 = 24/40 = x/60

Therefore, we obtain the following equations:

• Equation 1: 3/5 = 24/40
• Equation 2: 3/5 = x/60
• Equation 3: 24/40 = x/60

Clearly, the second and the third equation have the "x" variable included. Therefore, we will only focus on the second and third equations.

• 3/5 = x/60
• 24/40 = x/60

Note: We can choose any equation to solve for x. The value of x in both equations will be the same as 3/5 = 24/40.

Determining the "x" variable in Equation 2:

• ⇒ 3/5 = x/60
• ⇒ 5x = 60 × 3 [Cross multiplication]
• ⇒ 5x = 180 [Simplifying]
• ⇒ 5x/5 = 180/5 [Dividing]
• ⇒ x = 36 [Simplifying]

Determining the "x" variable in Equation 3:

• ⇒ 24/40 = x/60
• ⇒ 40x = 24 × 60 [Cross multiplication]
• ⇒ 40x = 1440 [Simplifying]
• ⇒ 40x/40 = 1440/40 [Dividing]
• ⇒ x = 36 [Simplifying]

Therefore, the value of "?" is 36.

Answer 2

? = 36

Explanation:

Knowing that 3/5 and 24/40 is equal

Therefore we can either use:

3/5 = ?/60 or 24/40 = ?/60

I will use 3/5 = ?/60

Let ? = x

Hence we have

3/5 = x/60

Multiply both sides by 10

6 = x/6

Multiply both sides by 6

x = 36

Therefore, the question mark = 36

Let's check the answer by Simplifying the fraction:

3/5 = 36/60

3/5 is in already simplify

36/60 simplify = 3/5

3/5 = 3/5

Thus, the question mark = 36
