Today Jamal had a spelling test. There were 21 words on the test. Jamal spelled two-thirds of them correctly. How many words did Jamal spell correct?

2/3 of 21= 2*21/3=14

Right?

Right

To find out how many words Jamal spelled correctly, we need to calculate two-thirds of the total number of words on the test.

First, we need to determine two-thirds of 21. To do this, multiply 21 by 2 and then divide the result by 3.

Mathematically,
Two-thirds of 21 = (2/3) * 21 = (2 * 21) / 3 = 42 / 3 = 14

Therefore, Jamal spelled 14 words correctly on his spelling test.
