4 divided by x equals 10 = 0.4
You can use two methods: the sequential factoring or the smaller number method. Sequential (factor tree): 100 divided by 2 equals 50, divided by 2 equals 25, divided by 5 equals 5. 2 x 2 x 5 x 5 = 100 Smaller factors: 100 = 10 x 10 and 10 = 2 x 5 so 100 = (2 x 5) x (2 x 5) = 2 x 2 x 5 x 5
