After the party, there was 0.5 of the pizza left. angela ate 0.2 of the leftover pizza. angela said that she ate 0.01 of the whole pizza but cal and martha disagreed. cal said it was 0.10 and martha said it was 0.1 mark all statements that are true. true not true angela is correct. cal is correct. martha is correct. nobody has the correct answer.

For one thing, Cal and Martha are technically in agreement; 0.1 and 0.10 are the exact same value. To see whether they're right, or whether Angela had it correct, let's take a look at the numbers 0.5 and 0.2.

As fractions, those two values would be  and , or  and  when reduced. When you cut the original pizza in half, you cut it into 2 equal slices. Cutting each of those two pieces into 5 equal pieces, we get a total of 5 x 2 = 10 equal slices. So, taking one of those slices at that point - as Angela did - would be taking  - or 0.1 - of the whole pizza.

So, both Cal and Martha are correct.
