Question

Mabel has a total of 54 decorative beads. Some are black and some are white. The ratio of the number of black beads to the number of white beads is 7 : 2. How many more black beads than white beads are there?

Answer 1

So 7+2=9, 54 divided by 9 = 6. 6 times 7 = 42, and 6 times 2= 12.
There are 42 Black beads and 12 White beads.
So overall there are 30 more black beads than white
