You could multiply the 146 by 2 to give 292 and as 20 is 10 tens 2, just add a zero at the end of that, to give 2920.
1 times 20, 2 times 10, and 4 times 5
146 x 20 = 2920
20/30 times(multiply) 100 = 66.67%
first you multiply twelve times eight, this equals 96. then multiply 96 and 20. 96 times 2 is 192 then you add the zero you took of of the 20. that makes 1920!
320
Yes and to get it you multiply 20 times 20. 20x20=400
146 multiplied by 129 = 18,834
2÷ by what equals 146
210 x 146 = 30660
146 x 67 = 9782
Exactly 146 times
Two methods can be used here; take your pick. 1) Multiply 2 times the number, multiply 1/2 times the number, add the results. Example: 2 1/2 times 20 = (2 x 20) + (1/2 x 20) = 40 + 10 = 50. 2) Convert the mixed fraction into an improper fraction, than multiply. Example: 2 1/2 x 20 = 5/2 x 20 = 100/2 = 50.
