If this were an equivalent fraction problem, how would you find the value of x?
Think about what values would go in a Giant One to turn tenths into fifteenths.
This problem becomes x(1.5) = 6. What number multiplied by 1.5 gives 6?
You can also notice that 10 is two-thirds of 15 and think about what number is two-thirds of 6.
x = 4
This problem is very similar to part (a).
x = 6
How could you use a Giant One to find the value of m?
