If you want to work it in your head, try this: 21 = 20 + 1, and if we multiply we get this: 21 x 5 = (20 + 1) 5 = (20 x 5) + (1 x 5) = (100) + (5) = 105 That's the distrubutive property of multiplicatin in action. We broke the 21 down into 20 + 1, and then when we multiply that by 5, we have to multiply each "component" of the number (that is, both the 20 and the 1) by 5 to get the answer. The 5 is "distributed" over the components that make up the 21, which are (in this case) the 20 and the 1. Each one is multiplied by 5 and then the two numbers are added up to get an answer.
2 and 5/8 times
21 will divide into 100 four times. This will leave a remainder of 16.
Three (3.9524) times.
108 ÷ 21 = 5 with remainder 3.
21 will go into 4 four times and the big number which is six will go on the other side and that fraction is 7/8
21-5= 16x3= 48 The correct answer of 21 minus 5 times by 3 is 48.
2 and 5/8 times
5 goes into 21 4.2 times or 4 with remainder 1.
21 = 105/5
21 will divide into 100 four times. This will leave a remainder of 16.
21 times, remainder1
5 times is wrong
Three (3.9524) times.
108 ÷ 21 = 5 with remainder 3.
21 x 1/5 = 4 1/5 or 4.2
5 times, and one left over
21 times, with 3 left over.21 times with a remainder of 3
