Question

Which expression represents another method of computing the product given below?6.15*(-3.11)

Answer 1

(6 x (-3.11)) + (0.15 x (-3.11))

Explanation:

In the given expression, the term 6.15 can be written as follows.

6.15 = 6 + 0.15

Apply the distributive property.

6.15 x (3.11) = (6 x (-3.11)) + (0.15 x (-3.11))

So, another method of computing the given product is given by the following expression.

6 x (-3.11)) + (0.15 x (-3.11))

Answer 2

The expression that represents another method of computing

Is

615/100*(-311/100)

Explanation:

Given the expression in decimal form, we can convert this to factional form and perform product operations as an alternative computational method

6.15*(-3.11)= 19.13

In fraction 6.15 can be written as

615/100

In fraction -3.11 can be written as

-311/100

Hence The product can also be expressed as fractions

615/100*(-311/100)
