A jewelry store has 9/10 of an ounce of gold. They need to split it into 1/6 ounce groups. How many groups can they make?
Set up an equation like this where x is the number of groups:
\(\frac{1}{6}\)x = \(\frac{1}{6}\)
Now just solve the equation by dividing by \(\frac{1}{6}\) (or multiplying by the reciprocal: 6).
x = 27/5 = 5 and 2/5ths
Since you can't have 5 and 2/5ths groups, the answer is just the biggest number of groups that could be made without resorting to a fraction.
So just 5 groups.
the amount of gold present is - 9/10 of an ounce of gold
from this gold they have to split into groups of 1/6 ounce each
so we have to divide 9/10 ounce in to groups of 1/6
for this we have to divide 9/10 by 1/6
\(\frac{9}{10} / \frac{1}{6}\)
when dividing fractions we mutiply the first fraction by the reciprocal of the second fraction
reciprocal of 1/6 is - 6/1
\(\frac{9}{10}*\frac{6}{1} = \frac{54}{10} = 5.4\)
so the number of groups that can be made is 5 whole groups with 0.4 ounce of gold remaining
the whole number of groups that can be made - 5
