Find the sum of the two fractions show your work 3/8 and 1/2​
Romashka [77]

Answer: 7/8

Step-by-step explanation: Notice that 1/2 and 3/8 are unlike fractions. Our first when adding unlike fractions is to get a common denominator.

The common denominator of 2 and 8 will be the least common multiple of 2 and 8 which is 8.

To get an 8 in the denominator of 1/2, we multiply the numerator and the denominator by 4 which gives us 4/8.

Notice that 3/8 already has an 8 in the denominator so we leave it how it is.

Now we are adding like fractions.

To add like fractions, or fractions that have the same denominator, simply add the numerators and keep the original denominator.

So here, if we add the numerators we have 4 + 3 which gives us 7 and we put this over our original denominator which is 8 and we have our answer. Also, notice that 7/8 is in lowest terms so it's our final answer.

This means that 3/8 + 1/2 = 7/8

How do you write 3.74 x 10-4 in standard form?
BaLLatris [955]

Answer:

#3.77xx10^3=37700#

Explanation:

In scientific notation, we write a number so that it has single digit to the left of decimal sign and is multiplied by an integer power of #10#.

In other words, in scientific notation, a number is written as #axx10^n#, where #1<=a<10# and #n# is an integer and #1<=a<10#.

To write the number in normal or standard notation one just needs to multiply by the power #10^n# (or divide if #n# is negative). This means moving decimal #n# digits to right if multiplying by #10^n# and moving decimal #n# digits to left if dividing by #10^n# (i.e. multiplying by #10^(-n)#).

In the given case, as we have the number as #3.77xx10^4#, we need to move decimal digit to the right by four points. For this, let us write #3.77# as #3.770000# and moving decimal point four points to right means #37700.00#

Hence in standard notation #3.77xx10^3=37700#
