L.C.M. of the denominators is 10.

So, keep the denominators and subtract the numerators.

\frac{5}{10} -\frac{3}{10} =\frac{5-3}{10}

=\frac{2}{10}

Now, simplify the fraction.

To simplify, divide the numerator and the denominator by the common factor 2.

\frac{5}{10} -\frac{3}{10} =\frac{2}{10}

=\frac{1}{5}

Hence, \frac{5}{10} -\frac{3}{10} =\frac{1}{5}.

Last year at a certain high school, there were 50 boys on the honor roll and 100 girls
Sedbober [7]

there were 145 boys on the honor role and 60 girls equally given a total number of 205. This year, the number of boys decreased by 20% = 0.2*145=29

145-29=116

116 is this year number of boys on honor role

For girls.

=0.25*60=15

60-15=45

45 is this year number of girls on honor role.

Total number of students on honor role this year is 116+45 =161

Percentage of decrease = 1 -(161/205)*100% =( 1-0.785)*100

= 0.215*100

= 21.5%

Hudson went into a grocery store and bought 5 peaches and 7 mangos, costing a total of $16. Austin went into the same grocery st
strojnjashka [21]

Answer:

the mango cost 1.75$ each and the peach 0.75$

Step-by-step explanation:

M= mango

P=peach

we know that Hudson spend 16$ buying 7 mangos and 5 peaches. So we can write the equation

(1) 16=7M+5P---> (2)P=(16-7M)/5

and we know that Austin spend 14.50 buying 4 mangos and 10 peaches.

we write the equation

(3)14.50=4M+10P

and we replace the P with the equation (2)

14.5=4M+10*(16-7M)/5

14.5=4M+2*(16-7M)

14.5-32=4M-14M

M=1,75$

and now we replace M in eq. (2)P=(16-7*1.75)/5=0.75$
