Laura shades 60 squares on her hundredths grid And Billy shades 50 squares on his hundredths grid. Write the decimal number that

Andre45 [30]

Answer:

$Laura = 0.60$

$Billy = 0.50$

0.60 > 0.50

Step-by-step explanation:

Given

$Laura = 60\ shades$

$Billy = 50\ shades$

Required

Represent using decimal number and compare

From the question, we understand that there are 100th grids;

So:

$Laura = \frac{60}{100}$

$Laura = 0.60$

$Billy = \frac{50}{100}$

$Billy = 0.50$

Comparing both decimals;

Since 0.60 is greater than 0.50, we have:

0.60 > 0.50
