In am election, Mrs.Jones received 70% of the 1,500 votes cast. How many votes did Mrs. Jones receive
WARRIOR [948]

Hello!

To calculate how many votes Mrs. Jones had received, you would begin by converting 70% into a decimal, and then multiplying that decimal by the total number of votes.

Remember, all percentages are out of 100. So, 70/100 can be simplified into 7/10. As a decimal, 7/10 would be 0.7.

Next, we multiply 0.7 by the total number of votes, which is 1,500.

0.7 · 1500 = 1050

Therefore, in this election, Mrs. Jones received 1,050 votes out of the total 1,500 votes casted.
