Sandy. You take 3/10 and make it a decimal and that gives you .3 3/7 gives you .4 and 3/9 gives you .3.
Answer:
Sandy ate more.
Step-by-step explanation:
Kim ate [tex]\frac{3}{10}[/tex] of a bag .
Sandy ate [tex]\frac{3}{7}[/tex] of a bag.
Jeff ate [tex]\frac{3}{9}[/tex]of a bag
Take the lcm of denominators
LCM of 10,7 and 9 is 630
Make the denominators of fractions same
[tex]\frac{3 \times 63}{10 \times 63}=\frac{189}{630}[/tex]
[tex]\frac{3 \times 90}{7 \times 90}=\frac{270}{630}[/tex]
[tex]\frac{3 \times 70}{9 \times 70}=\frac{210}{630}[/tex]
So, [tex]\frac{189}{630}<\frac{210}{630}<\frac{270}{630}[/tex]
[tex]\frac{3}{10}<\frac{3}{9}<\frac{3}{7}[/tex]
So, Sandy ate more.
