tolong dijawab ya nanti saya doain masuk surga amin

(1). 3/5 = 0,6
0,89 + 0,6 = 1,49

(2).2/5 + 45℅ + 0,75 =
0,4 + 0,45 + 0,75 = 1,6

(3). sisi siku siku

(4).2 1/6 × 2 1/5 = 13/6 × 11/5 = 143/30

(5).kerucut

(6).0,9 : 0,75 = 9/10 : 75/100
= 9/10 × 100/75 = 90/75
= 6/5 = 1 1/5

(7).< C = 70°
< A = 90°
< B = .........?
180 - ( 70 +90 = 160) = 20°


(9). 1 simetri

(10).60℅ = 54.000
100℅ = ..........?
54.000 : 60 = 900
1℅ =900
100 % = 900 × 100 = 90.000

1. 3/5+89/100=60/100+89/100=149/100
                      =1,49
2.2/5=0,4
        =0,4+0,45
        =0,85-0,75
        =0,10

3.sisi AB

4.13/6×11/5=143/30=4 23/30

5.bangun kerucut

6.9/10×100/75=900/750=90/75=1 15/75=1 1/5

7.maaf gak tau

8.6/5×7/15=42/75×4/7=168/525=24/75

9. 1 simetri lipat

10.60/100×54.000,00=32.400,00

maaf ada yang gak dijawab

semoga benar
amin............................................
