Henry is making a recipe for biscuits. A recipe calls for 3 / 10 kilogram flour and 8 / 100 kilogram sugar. If Henry measures correctly and combines the two amounts, how much flour and sugar will he have?

38/100

Step-by-step explanation:

To combine the amounts, add the fractions with a common denominator.

3/10 kilogram flour is 30/100.

8/100 kilogram of sugar.

Both now have the same denominator. Add the numerators to find the total.

30/100 + 8/100 = 38/100
