Answer:
The decimal form of this rational number is .
Step-by-step explanation:
a) Let a rational number. From statement we understand that
represents the numerator, while
corresponds with the denominator of the rational number. Hence,
is 3 and
is 11.
b) The decimal form is obtained by dividing by
, we presented the step needed to determine the decimal form:
i) Multiply the numerator by 10:
Dividend: 30/Divisor: 11/Known result: 0. /Residue: N/A
ii) Multiply the divisor by 2 and subtract from the dividend:
Known result: 0.2 /Residue: 8
iii) Multiply the residue by 10:
Known result: 0.2 /Residue: 80
iv) Multiply the divisor by 7 and subtract from the residue:
Known result: 0.27 /Residue: 3
v) Multiply the residue by 10:
Known result: 0.27 /Residue: 30
vi) Multiply the divisor by 2 and subtract from the residue:
Known result: 0.272/Residue: 8
vii) Multiply the residue by 10:
Known result: 0.272 /Residue: 80
viii) Multiply the divisor by 7 and subtract from the residue:
Known result: 0.2727/Residue: 3
We have notice that the decimal form of is a periodical decimal number. Hence, we conclude that decimal form of this rational number is
.
Answer: An ostrich can walk with a speed of 2 miles per hour.
Step-by-step explanation:
Speed of roadrunner bird=14 miles per hour
Let x be the speed of ostrich egg.
Given that : A the greater roadrunner bird can run 7 times faster than an ostrich can walk.
⇒ Speed of roadrunner bird=7x
⇒7x= 14 miles per hour.
Therefore, speed of ostrich egg=2 miles per hour.
