Maddie has a new beaded necklace. 70% of the 30 beads on Maddie's necklace are blue. How many blue beads are there on Maddie's necklace?)

Answer 1

Answer 2

70% of 30 is 21, so there are 21 blue beads on Maddie's necklace.

70% converted to a decimal is 0.7. On your calculator, type in 0.7 times 21, or, by hand, multiply 7 by 30 and move the decimal point to the left once.
