It doubles each number
Multiples of 5 are 5, 10, 15, 20, 25, 30, 35, 40, 45, 50... Multiples of 10 are 10, 20, 30, 40, 50, 60, 70, 80, 90, 100... The pattern is that every other multiple of 5 is also a multiple of 10.
These may help you answer your questions: 1, 2, 4, 5, 8, 10, 20 and 40.
1, 2, 4, 5, 8, 10, 20, 40 , -1, -2, -4, -5, -8, -10, -20, -40
The factors of 40 are 1, 2, 4, 5, 8, 10, 20 and 40The factor pairs of 40 are 1 x 40, 2 x 20, 4 x 10, and 5 x 8.The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40 .A factor = any number which can be divided into the given number with no remainder ie 1, 2, 4, 5, 8, 10, 20, 401, 2, 4, 5, 8, 10, 20, 40
20,40,60 Proof (20)(20/4=5)(20/5=4)(20/10=2) And (40)(40/4=10)(40/5=8)(40/10=4) And (60)(60/4=15)(60/5=12)(60/10=6)
40/10 = 20/a 4= 20/a 20/4 = a a= 5
The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.
1 2 4 5 8 10 20 40 and 80
Factors are numbers you can multiply together to get another number. 40: 1, 2, 4, 5, 8, 10, 20, 40
40 is divisible by- 1,2,4,5,8,10,20, and 40
well, half of 40 is 20. 20 divided by 2 = 10 and 40 divided by 2 = 20 so now you have 10 over 20. then: 10 dived by 2 = 5 and 20 dived by 2 = 10 so now you have 5 over 10, and 5 is half of 10 so it is 1 over 2.
40 does.
