Answer:
7/53 or Alternative form 0.1296
Step-by-step explanation:
convert the mixed number to an improper fraction 2 with 7/10 turns to 27/10
reduce the number with greatest common divisor 3: 1/5*7/4 divided by 27/10
to divide by a fraction, multiply by the reciprocal of the fraction: 1/5*7/4*10/27
reduced the numbers with greatest common divisor 5: 7/4*2/27
reduced the numbers with the greatest common divisor 2: 7/2*1/27
multiply the fractions going side ways. 7/54
A<b<c
b is the square root of 20
if we square everybody
a²<b²<c²
if we say that b²=20 then
a²<20<c²
find a and c
2^2=4
3^2=9
4^2=16
5^2=25
16<20<25
sqrt both sides
4<√20<5
somewhere between 4 and 5
closer to 16 than 25
