Answer:Look at the 2nd significant digit that the number has.
In a decimal, the first significant digit is the first non-zero digit. The 2nd significant digit is the digit after the first.
if it is less than 5 then round the number down by removing the rest of the number after the 1st significant digit and filling in with zeros;
if it is 5 or more then round the number up by adding one on to the 1st digit and removing the rest of the number and filling in with zeros.
Step-by-step explanation:
8726 rounds up to 9000, because the 2nd significant digit is a 7.
73.283 rounds down to 70 because the 2nd significant digit is a 3.
152 rounds up to 200 because the 2nd significant digit is a 5.
0.003826 rounds up to 0.004 because the 2nd significant digit is an 8.
0.60828 rounds down to 0.6 because the 2nd significant digit is a 0.
Answer:
Step-by-step explanation:
Let the two numbers be x and y
x = y - 5......(1)
2y = 3x.......(2)
Putting (1) into (2)
2y = 3(y - 5)
2y = 3y - 15
Collecting like terms
2y - 3y = -15
-y = -15
y = 15
Putting y = 15 in (1)
x = y - 5
x = 15 - 5
x = 60
7/24 is in simplest form because you cant divide it by anything to reduce it.
Reduce by dividing top and bottom by 7, =7/15
