$5 (7.1) = 35.5$ $5(7.1) = 35.5$

The distributive property comes in two forms:

Left distributive property:

$a (b + c) = a b + a c$ $a(b+c) = ab+ac$

Right distributive property:

$(a + b) c = a c + b c$ $(a+b)c = ac+bc$

We can use the left distributive property to find:

$5 (7.1) = 5 (7 + 0.1) = (5 \cdot 7) + (5 \cdot 0.1) = 35 + 0.5 = 35.5$ $5(7.1) = 5(7+0.1) = (5*7)+(5*0.1) = 35+0.5 = 35.5$

How do you use the distributive property to multiply 5(7.1)5(7.1)5(7.1)?
