Step-by-Step Solution

We rewrite the innermost parentheses in fraction form:

10/(7:92)= 10/(7:\frac{9}{2})=

We convert the parentheses into a multiplication exercise through inverting the fraction:

10/(7×29)= 10/(7\times\frac{2}{9})=

We add the 7 to the numerator for the multiplication exercise:

10/(7×29)=10:7×29 10/(\frac{7\times2}{9})=10:\frac{7\times2}{9}

We convert the exercise into a multiplication by inverting the fraction:

10×97×2= 10\times\frac{9}{7\times2}=

We add the 10 to the numerator for the multiplication exercise:

10×97×2= \frac{10\times9}{7\times2}=

We break down the 10 into a simpler multiplication exercise:

5×2×97×2= \frac{5\times2\times9}{7\times2}=

We simplify the 2 in the numerator and denominator:

5×97=457 \frac{5\times9}{7}=\frac{45}{7}

We convert the fraction's numerator into a sum exercise:

42+37=427+37=6+37=637 \frac{42+3}{7}=\frac{42}{7}+\frac{3}{7}=6+\frac{3}{7}=6\frac{3}{7}

Answer

637 6\frac{3}{7}
