Answer:

Step-by-step explanation:

$\frac{a}{4}=\frac{b}{7}\\a=\frac{4b}{7} \\\frac{a-b}{b} =\frac{\frac{4b}{7}-b }{b} \\=\frac{4b-7b}{7b}\\ =\frac{-3b}{7b}\\ =\frac{-3}{7}$

Jonah runs 3/5 miles on Sunday and 7/10 miles on Monday.He uses the model to find that he ran a total of 1 mile. What mistake do

antoniya [11.8K]

Answer: He did not convert the fractions into the like fraction to add.

Step-by-step explanation:

Given: The distance Jonah runs on Sunday= $\frac{3}{5}$ miles

The distance Jonah runs on Monday= $\frac{7}{10}$ miles

The total distance he ran = $\frac{3}{5}+\frac{7}{10}\ miles$

Since both the fractions are not like , thus multiply 2 to the numerator and the denominator of the first fraction [to add fractions first convert them into like fractions], we get

The total distance he ran = $\frac{3\times2}{5\times2}+\frac{7}{10}\ miles$

$=\frac{6}{10}+\frac{7}{10}=\frac{6+7}{10}\\\\=\frac{13}{10}=1\frac{3}{10}\ miles$

The right answer is "The total distance he ran = $1\frac{3}{10}\ miles$ "
