3÷?=36
multiply both sides by 3 to figure out what "?" is
36*3=108
3÷108=36
?=108
The probability that the next 4 winners will all be 7th grade students is 3/4
The number of patches that Leia can cut from 32 pieces of the fabric measuring 18 cm by 10 cm will be as follows:
Number of pieces=[total area of fabric]/[area of patch]
area of fabric=18×10=180 cm²
Area of 32 patches=180×32=5760 cm²
Area of patch=45 cm²
Number of patches=5760/45=128 patches
