A quick way to multiply a three-digit number by a two-digit number is by using the long multiplication method. Here are some for you to try (there are some multiplications with four-digit numbers in here, but don’t worry, the method is still the same!). Use the boxes to help you set out your numbers correctly!
When multiplying two fractions together, you quite simply multiply the numerators and then multiply the denominators. Work out the answers to these number sentences by multiplying both the numerators together and both the denominators together. Shade the diagram to show that you have found a fraction of a fraction.
Melissa has checked her multiplications by using division. Which calculations do you think she used? Match the correct pairs of multiplication and divisions.
