Question

Which of the following is a true statement 3/4<4/6. 11/15<4/5. 5/6>10/12 8/16=1/4

Answer 1

we can check each options

(A)

$\frac{3}{4}<\frac{4}{6}$

we can cross multiply it

$3*6<4*4$

$18<16$

this is not true

(B)

$\frac{11}{15}<\frac{4}{5}$

we can cross multiply it

$11*5<4*15$

$55<60$

this is true

(C)

$\frac{5}{6}>\frac{10}{12}$

we can cross multiply it

$5*12>6*10$

$60>60$

this is not true

(D)

$\frac{8}{16}=\frac{1}{4}$

we can cross multiply it

$8*4=16*1$

$32=16$

this is not true

Answer 2

here in order to determine which are true statements let us find lcd of each fraction

3/4<4/6.

lcd of 6 and 4 is 12

converting each denominator to 12

9/12<8/12

now comparing the numerator 9<8, which is not true

so 3/4<4/6 is not true.

11/15<4/5

lcd of 15 and 5 is 15 here

so we have 11/15<12/15

comparing numerators 11<12 which is true

so 11/15<4/5 is true

5/6>10/12

lcd of 6 and 12 is 12

10/12>10/12

10>10 is false

so 5/6>10/12 is not true

8/16=1/4

lcd of 16 and 4 is 4

so 8/16=4/16

which are not equal

so 8/16=1/4 is not true statement
