Answer 1

Explicación paso a paso:

sabemos que la fórmula para calcular área es;

A = base × altura.

1. X = 12,62cm² / 5.72cm = 2.2062937063 cm
2. X = 9.02 cm² / 4.3 cm = 2.0976744186 cm
3. X= 13.46 cm² / 2.34 cm = 5.7521367521 cm

45/100 × 50 = 9/20×50 = 22.5

4/6×140 = 93.3 periódico.

¼×87= 21.75

6/10×40= 3/5×40 = 120/5= 24

⅕× 400 = 80

45/100×130= 9/20×130= 58.5

32/100×120= 16/50=8/25×120 = 38.4

3/9 × 8 = 2.666

13/10 × 48 = 62.4

⅓ × 45 = 15

2/9 × 1000 = 222.22

7/10 × 110 = 77
