Answer: 1/4
1. Convert 1/1 into fourths
1/1 = 4/4
2. Evaluate
5/4 - 4/4 = 1/4
60 seconds in a minute
12 goes into 60, 5 times,
So 5 * 28 = 140
140 claps per minute
0.5 minute is 30 seconds, half a minute so divide by 2,
140/2 = 70
70 times every 0.5 minutes
Step-by-step explanation:
iii=90
41+i=90(opposite angle)
i=90-41
i=49
26+ii+49+41=180(straight line angle)
116+ii=180
ii=180-116
ii=64
50+25+iv=26+64(opposite angle)
75+iv=90
iv=90-75
iv=15
55+i+55=180(straight line angle)
110+i=180
i=180-110
i=70
ii=55(alternative angle)
