1 answer
To find the whole when it is known that 84 is 70% of it, you can set up a proportion based on the relationship between part and whole.
We know that:
\[ 70% = \frac{70}{100} \]
Let \( x \) be the whole. Thus, we can express the relationship as:
\[ \frac{84}{x} = \frac{70}{100} \]
To solve for \( x \), we can cross-multiply:
\[ 84 \cdot 100 = 70 \cdot x \]
This simplifies to:
\[ 8400 = 70x \]
Now, divide both sides by 70:
\[ x = \frac{8400}{70} = 120 \]
So, the whole is \( \boxed{120} \).
