Question

How many 4 1
2
inch strips can be made from 45 inches of shipping tape?

Answer 1

just divide the 45 by the 4½

thus
`\bf 45/ 4(1)/(2)\iff \cfrac{45}{4(1)/(2)}\implies \cfrac{(45)/(1)}{(4\cdot 2+1)/(2)}\implies \cfrac{(45)/(1)}{(9)/(2)}\implies \cfrac{45}{1}* \cfrac{2}{9}\implies \cfrac{45* 2}{1* 9}`
