Riley Anderson · Answer

#1 3/8 = 1.375# Decimal notation is a way of writing fractions which have their denominators as powers of #10# Change #1 3/8# into a fraction with a power of #10# in the denominator. It helps to know that #8 xx 125 = 1000# #1 + color(blue)(3/8xx125/125) = 1 + color(blue)(375/1000)# The whole number is #1# and the fraction part is #375/1000# #1 3/8 = 1.375#

To turn a fraction to a decimal you need to know some rules. #1 3/8# must be turned into an improper fraction. To do this you need to: #1# get the denominator (bottom number) #2# multiply it by your whole number and #3# add the numerator (top number) . So step #1and2# #8xx1# will give you #8# Step #3# #8+3# will give you #11# The next rule is to keep your denominator the same as it is on your given fraction which is #8# and on top for the numerator you need to have your total answer which is #11# Therefore: #11/8# is your fraction that needs to be turned into a decimal. To do this you simply d1vide 11 by 8 #11/8=1.375# Hope this gave you an idea of how to turn any fraction into a decimal. You can do this with any fraction. E.g. #4/8= 0.5# #9/45=0.2# #7/49=0.143#
