a)

False, because 2+6=8, but 3+6=9 not 12 and I need to add the same number to the numerator and denominator get a fraction with the same value

b)

True, because 8 is smaller than 12

c)

False, because 8 does not divide by three

d)

True, because 2x4=8 and 3x4=12, and I need to times/multiply the same number to the numerator and denominator to get a fraction with the same value

2.

Which fraction is bigger  59 or 815\frac{5}{9}\ or\ \frac{8}{15}  

a)

 59\frac{5}{9}  because 9-5=4 and 15-8=7 and 4 is less than 7

b)

 815\frac{8}{15}  because 8 is bigger than 5

c)

 59\frac{5}{9}  because it is equivalent to  5+159+15=2024\frac{5+15}{9+15}=\frac{20}{24} and  815=8+915+9=1724\frac{8}{15}=\frac{8+9}{15+9}=\frac{17}{24}   

d)

 59\frac{5}{9}  because  59=5×59×5=2545\frac{5}{9}=\frac{5\times5}{9\times5}=\frac{25}{45}  and  815=8×315×3=2445\frac{8}{15}=\frac{8\times3}{15\times3}=\frac{24}{45}  

3.

To calculate  725\frac{7}{25}  of $175 I have to calculate

a)

 175+725=18225\frac{175+7}{25}=\frac{182}{25}  

b)

 175725=16725\frac{175-7}{25}=\frac{167}{25}  

c)

 175×725=175×725=7×25×725=7×7=49175\times\frac{7}{25}=\frac{175\times7}{25}=\frac{7\times25\times7}{25}=7\times7=49  

d)

 257×175=149\frac{25}{7\times175}=\frac{1}{49}  

4.

 27+23=\frac{2}{7}+\frac{2}{3}=  

a)

 2+27+3=410\frac{2+2}{7+3}=\frac{4}{10}  

b)

 2×37×3+2×73×7=2021\frac{2\times3}{7\times3}+\frac{2\times7}{3\times7}=\frac{20}{21}  

c)

 2×27×3=421\frac{2\times2}{7\times3}=\frac{4}{21}  

d)

 2+37+3+2+73+7=1510=32\frac{2+3}{7+3}+\frac{2+7}{3+7}=\frac{15}{10}=\frac{3}{2}  

5.

 5658=\frac{5}{6}-\frac{5}{8}=  

a)

 5568=02=0\frac{5-5}{6-8}=\frac{0}{-2}=0  

b)

 58685668=312=42=2\frac{5-8}{6-8}-\frac{5-6}{6-8}=\frac{3--1}{-2}=\frac{4}{-2}=-2  

c)

 5×86×85×68×6=403048=1048=524\frac{5\times8}{6\times8}-\frac{5\times6}{8\times6}=\frac{40-30}{48}=\frac{10}{48}=\frac{5}{24}  

6.
