Given : The addition 21.4 + 15 + 17.17 + 4.003 by the rules for significant figures.
Solution: According to given numbers, let us count number of significant figures in each of the given numbers.
21.4 has three significant figures.
15 has two significant figures.
17.17 has four significant figures.
4.003 has four significant figures.
We have to round the final answer to the nearest tens place because 15 has only accurate to the ones place.
We can see that other numbers are accurate to the tenths, hundredths and thousandths places, respectively.
Let us add them as usually first,
21.4 + 15 + 17.17 + 4.003.
It gives 57.573.
Now, we need to round it to the ones place.
We get 58 as the final answer.
Given
Gina has 6 yards of ribbon.
She cuts the ribbon into pieces that each measures three fourths yard.
Find out how many pieces of three fourths yard does Gina have
To proof
let the number of pieces of the ribbon be x.
As given in the question
Gina has of ribbon = 6 yards
She cuts the ribbon into pieces that each measures three fourths yard
Than the equation becomes
solving the above equation
we get
x = 2 × 4
x = 8
Gina have 8 pieces of three fourths yard
Hence proved
