If a person spends 6 dollars on fruit. But spent 15 dollars in total. What percentage of the total did the person spend on fruit

$${\frac{{\mathtt{6}}}{{\mathtt{15}}}} = {\frac{{\mathtt{x}}}{{\mathtt{100}}}}$$

6*1.00=6

$${\frac{{\mathtt{6}}}{{\mathtt{15}}}} = {\mathtt{0.4}}$$

move the . on .4 twice to the right, equals 40

overall, the anonymous person spent 40% of the $15 on food
