Given:
47% of 89
Exact solution is : 0.47 * 89 = 41.83
Estimates: you round the number to the nearest tens.
47% can be 50% ; 89 can be 90
0.50 * 90 = 45
50% is the same as 1/2
1/2 * 90 = 45
90/2 is also applicable to estimate for the above figure. 90/2 = 45
$4.44/12 Popsicles = $0.37/Popsicle.
The Popsicle unit rate it $0.37/Popsicle
I hope this helped :3
the question doesn't say how many dolls. there would be an infinite number.
But we'll just form the equation for the nth doll.
Largest doll = 12 inches
2nd doll = (12) x 0.7
3rd doll = (12 x 0.7) x 0.7
4th doll = [(12 x 0.7) x 0.7) x 0.7
OK, We now see the pattern. Each successive doll is mult by the previous
doll height x 0.7
the Nth doll, 12 is mult by 0.7(n-1)
So, the height of the nth doll can be expressed as: 12 x 0.7(n-1)
example: 4th doll = 12 x 0.7(4-1) = 12 x 0.73
10th doll = 12 x 0.7(10-1) = 12 x 0.79 etc
