Answer:
45 days
Step-by-step explanation:
300 men = 90 days
the percentage of food consumed by one man
= ( 90 / 300 ) * 100
= 30% = 0.3
After 40 days
150 men remain to consume at 30%
determine the number of days the remaining food will last ( x )
= x / 150 = 0.3
therefore ; X = 150 * 0.3 = 45 days
Please note that in the original problem you have horizontal division symbols:
4 1 3
--- x - ---- = -----
5 10 10
On the other hand, you have typed <span>4/5x-1/10=3/10. To avoid ambiguity you must enclose the fractions inside parentheses:
</span><span>(4/5)x- (1/10) = (3/10). Otherwise, your reader will not know for sure whether you meant 4 / (5x) or (4/5)x.
</span><span>After you've typed in these parentheses, your next task is to mult. all the terms of this equation by 10, to remove the fractions. Result:
8x - 1 = 3, or 8x = 4, or x = 1/2 (answer)</span>
Answer:
m= 0.3
Step-by-step explanation:
10.1 = 8 + 7m
-8 -8
2.1 = 7m
2.1/7 = 0.3
