Question

About how far can a motor boat can go in six hours? ​

Answer 1

Answer:

The ratio of the number of the boys to the number of

girls in a school of 500 students is 3 : 2. If 50 new

girls are admitted in the school, find how many new

boys may be admitted so that the ratio of the number

of boys to the number of girls may change to 7 : 5.
