3/7 of 56 = n
I took 3/7 = 0.428571 and timed it by 56 and got 23.999998. rounded to 24, n= 24 is this right?
Please help...
$\displaystyle \frac{3}{7}\cdot 56=n$
to multiply them together rewrite 56 as a fraction over 1
$\displaystyle \frac{3}{7}\cdot \frac{56}{1}=n$
$\displaystyle \frac{3 \cdot 56}{7 \cdot 1}=n$
$\displaystyle \overbrace{\frac{3 \cdot \not {56}}{\not 7 \cdot 1}}^{8}=n $
$\displaystyle 3 \cdot 8=24=n$
Remember fractions are our friends
