2 1/10:
= 2 + (1 ÷ 10)
= 2 + 0.10
= 2.1
2/5 multiply times 2(because .1=1/10). that equals 4/10 in decimal form that is .4(again, because .1=1/10).
same as 1/10 = .1
0.5 = 1/2
You can, but only if the decimal is 1.0+. okay, say your decimal is 1.2, then you put the 2 over 10 and keep the one as a whole so it looks like 1 2/10 or 1 1/5
1/5 = 2/10 = 0.2
2 and 1/100 = 2.01
2/20 = 1/10 = .1
1.2
.10 or .1 you move the decimal 2 places to the left
2/5 multiply times 2(because .1=1/10). that equals 4/10 in decimal form that is .4(again, because .1=1/10).
2.1 = 2 1/10
10.5
1/10 * 2/10 = 2/100 = 0.02
1 and 2 tenths can be written as a decimal as 1.2. This is because the "1" represents one whole unit, and the "2 tenths" represents 0.2 when converted to a decimal. So, when combined, it becomes 1.2.
10 in binary is equivalent to 2 (decimal). 10 (ten) decimal is equivalent to 1010 (binary) [ 1*8 + 0*4 + 1*2 + 0*1] = 8 + 2 = 10(ten)
It is very easy. 20 out of 100 simplified is 1/5. 1/5 is the same as 2/10. 2/10 in decimal form is .2.
In the decimal (base-10) system, 2 is. In the binary (base-2) system, 10 is.
