Answer: He did not convert the fractions into the like fraction to add.
Step-by-step explanation:
Given: The distance Jonah runs on Sunday= [tex]\frac{3}{5}[/tex] miles
The distance Jonah runs on Monday= [tex]\frac{7}{10}[/tex] miles
The total distance he ran = [tex]\frac{3}{5}+\frac{7}{10}\ miles[/tex]
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 = [tex]\frac{3\times2}{5\times2}+\frac{7}{10}\ miles[/tex]
[tex]=\frac{6}{10}+\frac{7}{10}=\frac{6+7}{10}\\\\=\frac{13}{10}=1\frac{3}{10}\ miles[/tex]
The right answer is "The total distance he ran =[tex]1\frac{3}{10}\ miles[/tex]"
