Answer:
the answer is B
Step-by-step explanation:
If you round 1,903.003 and 198.7 to the nearest hundred you will get 1900 and 200.
1900 * 200 = 380000
Round 380000----400000
The best estimate is B. 400,000
Sample Response: First, the like terms had to be combined using the lowest common denominator (LCD). Then the subtraction property of equality was used to isolate the variable term. Finally, both sides of the equation were multiplied by the reciprocal of the coefficient to solve for a.
How many blocks will Colin run by the end of the sixth week?
A.
Use objects to model the problem.
Put out 1 chip to represent the blocks run in week one. Put out twice that amount for week two. Put out twice that amount (from week two) for week three. Do this 3 more times, putting out twice the amount from the previous week each time.
B.
Make a table.
In the first row, write first week - 2 blocks. In the next row, write second week - 4 blocks. In the third row, write third week -6 blocks. Continue this pattern for three more rows.
C.
Write a number sentence.
(1 + 2) × 6 = x
Add the number of blocks run in the first and 2nd week. Then multiply the sum by the number of weeks (6).
65% written as a fraction in simplest form is 13/20.
To express 65% as a fraction in its simplest form, you need to convert the percentage to a fraction with a denominator of 100 (since percentage means "per 100").
Divide the percentage value by 100:
65% = 65/100
Now, to simplify the fraction, find the greatest common divisor (GCD) of the numerator and denominator and then divide both by the GCD to get the simplest form:
The greatest common divisor of 65 and 100 is 5.
Divide both the numerator and denominator by 5:
(65 ÷ 5) / (100 ÷ 5)
= 13/20
So, 65% written as a fraction in simplestform is 13/20.
