calculista

we know that

1) Sam had [tex]\frac{4}{5}[/tex] yards of yarn

2) Sam used [tex]\frac{3}{8}[/tex] of the yarn

so

To calculate how many yards of yarn he used

Multiply [tex]\frac{4}{5}[/tex] by [tex]\frac{3}{8}[/tex]

[tex]\frac{4}{5} *\frac{3}{8} =\frac{12}{40} \ yards[/tex]

Simplify

Divide by [tex]4[/tex] both numerator and denominator

[tex]\frac{12}{40}=\frac{(12/4)}{(40/4)}=\frac{3}{10}\ yards[/tex]

therefore

the answer is the option C

[tex]\frac{3}{10}\ yards[/tex]
