To prove

As given

There were n signers of the Declaration of Independence.

The oldest was Benjamin Franklin, who was y years old. 7 is 10% of y and n is 80% of y.

10% is written in the decimal form.

= 0.10

80% is written in the decimal form.

= 0.80

As given

7 is 10% of y

Than the equation becomes

7 = 0.10 × y

y = 70

As given

n is 80% of y

Than the equation becomes

n = 0.80 × y

Put the value of y in the above

n = 0.80 × 70

n = 56

Therefore the 56 signers of the Declaration of Independence.
