A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.

The dual bar chart shows the hair colour of boys and girls in a year group.

Total = 6 + 9

Total = 15

⇒ 6 / 15

⇒ 2 / 5

Tamara invests $8000 in two different accounts. The first account has a simple interest rate of 3% and the second account has a

34kurt

Let Tamara invests amount $X$ in 3% account. She invests $8000-X$ in 2% account.

The interest after t years is given by

$I=Prt$ . After 1 year the two interests are equal, that is

$X(\frac{3}{100}) (1)=(8000-X)(\frac{2}{100}) (1)\\ 3X=2(8000-X)\\ 5X=16000\\ X=3200$

Thus, Tamara has to invest $\$3200$ in 3% account and $\$8000-\$3200=\$4800$ in 2% account.
