What is the product of 32/3 and 142/5

Answers

remember that
$(x)/(y)$ times $(z)/(t)$ = $(x times z)/(y times t)$
so we have
$(32)/(3)$ times $(142)/(5)$
that equals
$(32 times 142)/(3 times 5)$ = $(4544)/(15)$ =302 and 14/15

$(32)/(3) * (142)/(5) =(32*142)/(3*5)=(4544)/(15)=\boxed{\bf{302(14)/(15)=302.933333}}$
