How do I solve this ad show WORK for this? Please help...

Answer 1

Answer:

20%

Step-by-step explanation:

10 pieces

Austin ate 5/10 of the pizza (5 pieces)

5 pieces = 50%

Sharon ate 0.3 of the pizza (3 pieces)

3 pieces = 30%

50+30=80

100-80=20

20% left for Owen

Answer 2

Hey! For this problem, you just have to convert everything into decimals, and then percentages. To convert a decimal into a percentage, just move the decimal point two to the right and add a percent sign! For example:

The amount that Sharon ate is already converted into a decimal. 0.30 as a percentage is 30%, so she ate thirty percent of the pizza!

However, you still need to convert the amount of pizza that Austin ate from a fraction into a decimal. 5/10 is equivalent to 1/2, which is 0.50! Move the decimal point two to the right, and you get 50%.

50% plus 30% is 80%, which means that only 20% of the pizza is left for Owen!
