Answer:

The number is 2:7 :: 6:21

To find:

2:7 :: 6:?

Step 1:

Let us assume x in the proportional place and try to solve the ratio.

\frac{2}{7}=\frac{6}{x}

Step 2:

As we know, by using the formula:

\bold{\frac{a}{b}=\frac{c}{d}}

Step 3:

Cross multiply. So, the proportion will look like

2x = 42

Step 4:

Keeping X in LHS and bring ‘2’ to denominator of RHS.

X=\frac{42}{2}

X = 21.

Hence the required answer is 21.
