We have to write ,15 and 30 as a multiple of sum of whole numbers with no common factor.

→15= 13+2----13 and 2 are both prime that is no factor other than 1 and itself.

→30=13 +17---13 and 17 are both prime that is no factor other than 1 and itself.

Well theoretically speaking you could but that would take a long time and 15 and 30 have a common factor of 5 and 15. So I think for this one you can't since there are two common factors.

Answer:

480 pennies dated after 2000.

Step-by-step explanation:

1. Pennies dated before 1980 (x) - 25%,

All pennies (1,200) - 100%.

Then

$\dfrac{x}{1,200}=\dfrac{25}{100},\\ \\100x=25\cdot 1,200,\\ \\x=25\cdot 12=300.$

2. Pennies dated from 1980 to 2000 (y) - 35%,

All pennies (1,200) - 100%.

Then

$\dfrac{y}{1,200}=\dfrac{35}{100},\\ \\100y=35\cdot 1,200,\\ \\y=35\cdot 12=420.$

3. Rest pennies are dated after 2000, then

$1,200-300-420=480.$
