When converting decimals to fractions, remember that the numbers after decimal point will be the numerator while the denominator is determined by how many numbers appear.
for one number after decimal point (tenths) you would place the value over 10 [ex. 0.3 = 3/10]
two numbers after decimal point (hundredths) you place the value over 100 [.23 = 23/100]
now you add 7 to this value.
to do so, convert 7/1 to the LCD, which is 100.
7/1 * 100/100 = 700/100
now add .23 to 7
700/100 + 23/100 = 723/100
