1.) 1,4+27/40=.... 2.)3/5+12%=..... 3.)4/5+16%=... 4.)25%+7/10=... tolong ya kaka diesederhanakan duluya makasih

1,4 + 27/40
= 14/10 + 27/40
= 56/40 + 27/40
= 81/40
[tex] = 2 \frac{1}{40} [/tex]

3/5 + 12&
= 3/5 + 12/100
= 60/100 + 12/100
= 72/100
= 18/25 atau 0,72

4/5 + 16%
= 4/5 + 16/100
= 80/100 + 16/100
= 96/100
= 24/25 atau 0,96

25% + 7/10
= 25/100 + 7/10
= 25/100 + 70/100
= 95/100
= 19/20 atau 0,95

1) 1,4 + 27/40 = 1,4 + 0,675 = 2,075 = 2075/1000 = 83/40
2) 3/5 + 12% = 60% + 12%= 72% = 72/100 = 18/25
3) 4/5+16%= 80%+16%=96% =96/100 = 24/25
4) 25%+7/10 = 25%+70% = 95/100=19/20
