Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there are 2 numbers to the right of the decimal point, place the decimal number over 10 2 ( 100 ) . Next, add the whole number to the left of the decimal. 4 35 100 Reduce the fractional part of the mixed number. 4 7 20 Convert 4 7 20 to an improper fraction 87 20 |

Mrshape:4.35 has two decimal places (i.e hundredths) so converting to a fraction will be removing the dot and multiplying by 1/100 So 435/100 = 87/20 |
Re: Mr Shape Mathematics Give Away Saturday August 15 By 9pm by OSADNA009(m): 10:39pm On Aug 15, 2020 |
Mrshape:4 35/100=435/100=87/20 |

Mrshape:this is a recurring decimal, I.e 4.353535... For recurring decimal, the denominator is always 9 or 99 or 999 etc depending on the number of digits recurring.. In this case, our denominator is 99 since it is only two digits that are recurring (3 & 5) To get numerator, this will be (the main number without the decimal) minus (the actual number before the decimal). I.e 435 - 4 = 431 Therefore 4.35... = 431/99 |
