Question

which value below is closest to the solution to 4.8/y = 17.9/3.2(1) 0.86. (2) 1.22(2) 0.93. (4) 1.48

Answer 1

y = 0.86 (option 1)

Explanation:

GIven: 4.8/y = 17.9/3.2

$\begin{gathered} \frac{4.8}{y}=\frac{17.9}{3.2} \\ \text{cross multiply:} \\ 4.8(3.2)\text{ = y(17.9)} \end{gathered}$$\begin{gathered} 15.36\text{ = 17.9y} \\ \text{diviode both sides by 17.9:} \\ \frac{15.36}{17.9}=\text{ }\frac{\text{17.9y}}{17.9} \end{gathered}$$\begin{gathered} 0.858\text{ = y} \\ y\text{ = 0.858} \\ To\text{ the nearest hundredth, y = }0.86\text{ (option 1)} \end{gathered}$
