I may not fully understand the question but the value of 7 is 7. The value of 6 is 6 and the value of 9 is 9.
4 + 4 + 4 - 1 = 11? Was it supposed to be an equation? I am confused.
66 is the 100%
we can solve this problem by the rule of three.
Therefore:
66------------------------100%
x--------------------------150%
x=(66 * 150%) / 100%=99
Answer 150% of 66 is 99.
Other method:
150% of 66=1.5 *66=99
Answer: 150% of 66 is 99.
50 + (50 * 0.065) = the answer, sorry I don't have my calculator on me.
The full answer is 28.421856
