Assuming you mean 10/20, (10/20)/(4-5)=0.5/-1=-1/2 Assuming you mean 10.20, 10.2/-1=-10.2 Assuming you mean 10-20, (10-20)/(-1)=(-10)/-1=10
1/2= 10/20
20/10 × 20/1 = 40/1
There are two which are 1*10 = 10 and 2*10 = 20
In fact, 1/10 + 1/10 + 1/20 + 1/4 + 1/2 is equal to 1.1/10= 2/20 1/4= 5/20 1/2= 10/202/20+2/20= 4/20+1/20=5/20+5/20=10/20+10/20=20/2020/20=1
20/10 + 10 = 12 20/(10 + 10) = 1
The factors of 10 are 1, 2, 5, and 10. The factors of 20 are 1, 2, 4, 5, 10, and 20. Common factors of 10 and 20 are 1, 2, 5, and 10. 1,2,5,10. 1, 2, 5 and 10.
The factors of 20 are 1, 2, 4, 5, 10, and 20.
20 - 1, 2, 4, 5, 10, 20 10 - 1, 2, 5, 10
1 + 10 + 20 = 31
10 times as much as 20 is 1/10 of 2,000
1/4 + 1/10= (5 + 2)/20= 7/20
