What is (5/8)(4)(13) ?
hey you there if so can you plz help me with mine i am math HELP!:)
To find the total number of yards of yarn Mrs. Nelson needs, we need to multiply the amount of yarn used for one scarf by the number of scarves she plans to make.
First, let's determine the total amount of yarn used for one scarf. Mrs. Nelson uses 5/8 of a yard of each color yarn for one scarf. Since she uses four different colors, we need to multiply the amount used per color by the number of colors.
So, the amount of yarn used for one scarf would be:
(5/8) x 4 = 20/8 = 2.5 yards
Next, we need to multiply the amount of yarn used for one scarf by the number of scarves Mrs. Nelson plans to make.
She plans to make 13 scarves, so we multiply:
2.5 yards x 13 scarves = 32.5 yards
Therefore, Mrs. Nelson needs 32.5 yards of yarn to make 13 scarves.
