suppose the divisor and the dividend of a division problem are both fractions between 0 and 1, and the divisor is greater than t
Virty [35]

Divisor and Dividend are fractions lying between 0 and 1

Also, Divisor > Dividend

⇒ A smaller number is being divided by a larger number

Whenever a smaller number is divided by a larger number, the quotient is less than 1

E.g. Let divisor be \frac{4}{5} and dividend be \frac{2}{5}

\frac{4}{5} ÷ \frac{4}{5} = \frac{1}{2}, which is less than 1

Hence, the answer is that the quotient will be less than 1

max2010maxim [7]

Answer:

D. 29% and 22%

Step-by-step explanation:

The known percentages are 34% and 15%. Add these two together to get 49%. All four choices should add up to 100%. So subtract to find what remains:

100% - 49%

= 51%

We don't actually have enough information to determine the percents for summer and winter. BUT the only answer that adds up to 51% is answer D. 29% and 22%.
