Emma buys packets of coloured beads. purple beads are sold in packets of 8 red beads are sold in packets of 5 blue beads are sold in packets of 10 emma wants to buy an equal number of purple, red and blue beads. what is the smallest number of each colour emma could buy?

I dont know it help me

Step-by-step explanation:

The factors of each number are:

8 = 2 * 2 * 2

5 = 5 * 1

10 = 5 * 2 * 1

Therefore the smallest number that Emma could buy would be the product of the greatest common factors:

2 * 2 * 2 * 5 * 1 = 40

Hence Emma would buy 40 packets each.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

i believe the answer is d.
