Question

1. circle the factors of 15. 10, 3, 7, 5,

Explanation:

Step1: Find the factors of 15

The factors of 15 are the numbers that divide 15 evenly.
We know that \(15\div1 = 15\), \(15\div3=5\), \(15\div5 = 3\), \(15\div15=1\).
So the factors of 15 are 1, 3, 5, 15.

Step2: Check the given numbers

Among 10, 3, 7, 5:

• For 10: \(15\div10 = 1.5\) (not an integer, so 10 is not a factor of 15)
• For 3: \(15\div3 = 5\) (an integer, so 3 is a factor of 15)
• For 7: \(15\div7\approx2.14\) (not an integer, so 7 is not a factor of 15)
• For 5: \(15\div5 = 3\) (an integer, so 5 is a factor of 15)

Answer:

Circle 3 and 5.
