Answer:

38cm taller

Step-by-step explanation:

jack is 178cm tall

the ladder is 280cm tall

jack standing on the ladder is 280cm taller

so 178+280=458

the tree is 420cm tall

458>420

which means that jack is now taller than the tree standing in the ladder

458-420=38

so jack is 38cm taller than the tree standing on the top of the ladder

How to make a decimal a mixed number​
lianna [129]

Answer:Step 1: Write down the decimal divided by 1, like this: decimal1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

Step 3: Simplify (or reduce) the fraction

Example: Convert 0.75 to a fraction

Step 1: Write down 0.75 divided by 1:

0.751

Step 2: Multiply both top and bottom by 100 (because there are 2 digits after the decimal point so that is 10×10=100):

× 100

0.751 = 75100

right under arrow

× 100

(Do you see how it turns the top number

into a whole number?)

Step 3: Simplify the fraction (this took me two steps):

÷5 ÷ 5

right over arrow right over arrow

75100 = 1520 = 34

right under arrow right under arrow

÷5 ÷ 5
