Question

Which method can be used to find the product of 2.5 and 0.3?A. (2x0.5) 0.3=2 x0.3 +0.5=6+1.5 = 7.5B. (2+0.5) <0.3=2 x 0.3+0.5 x 0.3=0.6+0.15 =0.75C. (2+0.5) *0.3=2x0.3+0.5 0.3=6+0.15 = 7.5D. (2 x0.5) <0.3=2 x0.3+0.5 =0.6+1.5 =0.75

Answer 1

0.75

Explanation:$2.5\text{ }\times\text{ 0.3}$$\begin{gathered} 2.5\text{ = 2 + 0.5} \\ 2.5\text{ }\times\text{ 0.3 = (2 + 0.5)}\times\text{ 0.3} \\ =\text{ }0.3\text{(2 + 0.5)} \end{gathered}$$\begin{gathered} U\sin g\text{ distributive property:} \\ 0.3(2)\text{ + 0.3(0.5)} \\ 0.6\text{ + 0.15} \\ =\text{ 0.75} \end{gathered}$
