23870 divides by 38 is 628 remains 4
Round the factor of 2 to the nearest 10 then divide the 7 with the x for the two ninths
Answer: 21.78
Step-by-step explanation: Multiply 33 by .66. You will get 21.78.
It is easier to multiply. For example: 63 multiply by 7
63 x 7 = (60+3) x 7 = 60 x 7 + 3 x 7 = 420 + 21 = 441
Another example : 25 x 73
25 x 73 = (20+5) x (70+3) = 20 x 70 + 20x3 + 5x70 + 5x3
= 1400 + 60 + 350 + 15 = 1875
