2 Operations on Decimals Question 11, 7.2.A-16 HW Score: $26.47 \%, 9$ of 34 points Points: 0 of 1 Save
Suppose that to predict how tall a four-year-old will be at age 12, you multiply his or her height by 1.5 . If Allie is 105.5 cm when she turns 4 , predict how tall she will be when she turns 12.
Allie will be $\square$ cm tall. (Type an integer or a decimal.)

STEP 1

What is this asking? If we multiply Allie's height at age 4 by 1.5, how tall will she be at age 12? Watch out! Don't forget to include the units in your final answer!

STEP 2

1. Multiply Allie's height by the given factor.

STEP 3

Allie's height at age 4 is 105.5 cm.
We're told to multiply this by 1.5 to predict her height at age 12.
So, we have $105.5 \cdot 1.5$ .

STEP 4

Let's break this down!
We can do $105.5 \cdot 1.5 = 105.5 \cdot (1 + 0.5)$ .
This is the same as $(105.5 \cdot 1) + (105.5 \cdot 0.5)$ .
We know $105.5 \cdot 1 = 105.5$ .
Now, $105.5 \cdot 0.5$ is just half of $105.5$ , which is $52.75$ .
So, we have $105.5 + 52.75$ .

STEP 5

Adding those together, $105.5 + 52.75 = 158.25$ .
So, $105.5 \cdot 1.5 = 158.25$ .

STEP 6

Allie will be 158.25 cm tall when she turns 12.

STEP 1

What is this asking? If we multiply Allie's height at age 4 by **1.5**, how tall will she be at age 12? Watch out! Don't forget to include the units in your final answer!

STEP 2

1. Multiply Allie's height by the given factor.

STEP 3

Allie's height at age 4 is **105.5 cm**.We're told to multiply this by **1.5** to predict her height at age 12.So, we have 105.5⋅1.5105.5 \cdot 1.5105.5⋅1.5.

STEP 5

Adding those together, 105.5+52.75=158.25105.5 + 52.75 = 158.25105.5+52.75=158.25.So, 105.5⋅1.5=158.25105.5 \cdot 1.5 = 158.25105.5⋅1.5=158.25.
