Work: Calculate the value of equation 7/4×15+8/5×7+15×7/3+9×8/5 .
Question type: Mathematical calculation
Solution:
7/4×15+8/5×7+15×7/3+9×8/5
=1.75×15+8/5×7+15×7/3+9×8/5
=26.25+8/5×7+15×7/3+9×8/5
=26.25+1.6×7+15×7/3+9×8/5
=26.25+11.2+15×7/3+9×8/5
=26.25+11.2+105/3+9×8/5
=26.25+11.2+35+9×8/5
=26.25+11.2+35+72/5
=26.25+11.2+35+14.4
=37.45+35+14.4
=72.45+14.4
=86.85
Answer:7/4×15+8/5×7+15×7/3+9×8/5=86.85
