Answer:
1. 1
2. 1/10
3. 1 2/9
4. 3 1/2
5. 3 13/36
Step-by-step explanation:
1)7/12 + 3/12 + 2/12 =1
since pareho ang denominator nila deretso mo na sya i add
7/12+3/12+2/12= 12/12 or 1
2) 9/10-5/8= 11/40
dahil magkaiba ang denominator ng dalawa kailangan mo hanapin ang least common denominator or LCD
so
9/10 ×4/4 =36/40
5/8×5/5=25/40
then proceed to subtraction
36/40 - 25/40= 11/40
3)7/18 +5/6=1 2/9
LCD (1/1,3/3)
7/18 × 1/1 = 7/18
5/6 ×3/3=15/18
7/18+15/18= 22/18
since improper fraction sya or mas malaki ang numerator kaysa sa denominator i transform mo sya tru mix number by dividing the numerator and denominator
22÷18 = 1
this will be your whole number then the remainder will be the numerator wich is 4
then copy lang yung denominator wich is 18 this will give you 1 4/18
then simplify the fraction
4/18=2/9
this will give you the final answer of
1 2/9
4) 14 13/20- 11 3/10= 3 7/20
transform the mix number by multiplying the whole number then add the numerator
14 13/20 = 293/20
11 3/10= 113/10
LCD (1/1,2/2)
293/20 ×1/1= 293/20
113/10×2/2=226/20
293/20-226/20 =67/20 transform to mixed number
67/20=3 7/20
3 7/20 is the final answer
5)7 11/18 - 4 3 /12 =3 13/36
transform to improper fraction
7 11/18= 137/18
4 3/12 = 51/12
LCD ( 2/2,3/3)
137/18×2/2= 274/36
51/12×3/3= 153/36
274/36 - 153/36 = 121/36
change it to mix number
121÷36 =3 this will be the whole number
the remainder wich is 13 will be the numerator
and copy the denominator which is 36 with this you will get
3 13/36
