Divide and answer in simplest form: 1/3 divided by 5
disa [49]

Answer:

1/15

Step-by-step explanation:

1. You can divide 1/3 by 5 by changing the division symbol to its reciprocal, multiplication, and also divide by the reciprocal of the number after the symbol, 5. The reciprocal of 5 is 1/5.

2. Now you can do 1/3 multiplied by 1/5. Multiply the numerators by the denominators. The numerators are 1 and 1, so you multiply 1 by 1 which equals 1. Now you multiply the denominators, 3 and 5, which is equal to 15. If the numerator is now 1, and the denominator is 15, the new fraction is 1/15, getting you to your answer

Verdich [7]

Answer:

181 feets

Step-by-step explanation:

Given that:

Rate of change in water level = - 1.5 feets per month

Water level at beginning of May = 187 feets above sea level

Water level at the end of 4 months =?

Total change after four months = rate of change per month * number of months

= - 1.5 * 4 = - 6 feets

Hence water level after 4 months :

187 feets + (-6 feets)

187 feets - 6 feets

= 181 feets
