Decrease 1400 in the ratio 7:3 show calculation
Dmitry [639]

From the ratio computed, the numbers will be 420 and 980.

<h3>How to calculate the ratio</h3>

From the information given, we are to divide 1400 in the ratio 7:3. The smaller number will be:

= 3/(3+7) × 1400

= 3/10 × 1400

= 420

The larger number will be:

= 7/10 × 1400

= 980

Therefore, the numbers will be 420 and 980.
