Hanna baked a cake, she used 6 tenths of flour, 3 eggs and4 fifths of sugar. how man ingredients did she used ...

You have to add

Since the question wants to know how many ingredients she used, All we have to do is add them.

So as the question says, she used 6/10 flour, 3 eggs, and 4/5 sugar.

Now we have two fractions in this scenario. Let's make them have the same denominator. Either we divide 6/10 by 2 or multiply 4/5 by 2. Let's multiply.

4/5 * 2 = 8/10

Now we have 6/10, 3, and 8/10

Lets add them together.

3 + 6/10 = 3 and 6/10

Now 3 and 6/10 + 8/10 = 4 and 4/10

Simplify even further ...

and your answer will be 4 and 2/5

You need to add them up together so it will be 4 and 2/5
