Question

write the ratio of the second quantity with the first 10dozen pencils,90 pencils

Answer 1

Answer:

3:4

Step-by-step explanation:

Given the first quantity = 10 dozen pencils,

Given the second quantity = 90 pencils,

Required to find the ratio of second quantity to first quantity,

We should note that ratios are always calculated only after all the terms are expresses in the same units,

Here, first quantity is expressed in dozens where as second is not, so lets convert first before calculating the ratio,

We know 1 dozen = 12

=>first quantity = 10 dozen

= 10*12

=120 pencils.

Now, asking us to find the ratio of second quantity to first quantity

= 90:120

= 3:4 in its simplest form.
