Find the simple interest on $900 for 18 months at a rate of 9.5% per year

Anestetic [448]

To get the simple interest, we must use the formula: I= (p)(r )( t)
So, in this one we need to multiply $900x18x9.% and the answer will be $128.25. This is the amount of interest they are going to pay per year.

How do you find the answer to 8/10 divided by 1/5

kherson [118]

When fractions are divided by each other, you're really multiplying by the "multiplicative inverse". This is the fraction, but flipped.

$\frac{8}{10} \div \frac{1}{5} = \frac{8}{10} \times \frac{5}{1} \\\\So\\\frac{8}{10} \times \frac{5}{1} = \frac{40}{10} = 4$
