According to the problem, one-sixth of the number is 53.
(1/6) * N = 53
To find the number N, multiply both sides by 6:
N = 53 * 6
N = 318
Now, we need to find 57% of this number.
57% of N = 57/100 * N
57% of 318 = 0.57 * 318
Calculation:
0.57 * 318 = (0.5 + 0.07) * 318
= (0.5 * 318) + (0.07 * 318)
= 159 + (0.07 * 300) + (0.07 * 18)
= 159 + 21 + 1.26
= 180 + 1.26
= 181.26
Alternatively:
318 * 57 = 318 * (60 – 3) = 318 * 60 – 318 * 3
318 * 6 = 1908, so 318 * 60 = 19080
318 * 3 = 954
19080 – 954 = 18126
Since it’s 0.57, we need to place the decimal two places from the right.
Result = 181.26
