Daniel's age is X
Daniel's brother age is Y
X = 3 + ( 2Y )
Y = ( X - 3 ) / 2
In case of Daniel is 17
then his brother's age is = ( 17 - 3 ) / 2 = 7 years
I tried but couldn’t figure out sorry.
8/10*8/21
= 64/210
= 32/105
Yes, actually a couple:
different number with same digits (ex):
7.05
7.50
5.07
5.70
0.57
0.75
705
70.5
75
750
570
etc
hope this helps
Set up a proportion.
2/3 = 12/x. Cross multiply the proportion.
2x = 36. Solve for x.
x = 18.
